Compression Ring For Coaxial Cable Connector

Abstract

The present invention discloses an improvement in coaxial compression connectors for use, inter alia, in CATV, satellite, and home theater electronics. The connectors accept a large range of cable sizes, allow replacement of the holding or compression element to accommodate a range of sizes, and allow the connector to be reusable. The connector comprises an attachment nut, a tubular shank attached to the connector nut and extending rearwardly therefrom, a rigid tubular outer shell having a cylindrical axial bore attached to the nut, and a deformable compression slidingly and removably disposed between the axial bore of the rigid outer shell. The compression tube has an annular groove on the outer circumference thereof which causes the compression sleeve to buckle and deform inwardly in response to a longitudinal force applied to the compression tube. When the compression tube is fully advanced toward the nut, the connector securely grips a coaxial cable within the connector and creates a 360 degree moisture seal.

       7 . A coaxial cable connector comprising: (a) a connector nut; (b) a tubular shank having a leading end abutting said connector nut and a trailing end extending rearwardly from said connector nut; (c) a rigid outer shell concentrically overlying said tubular shank, said rigid outer shell having a leading end abutting said connector nut and a trailing end in opposition thereto and an axial bore therebetween; and (d) a deformable, tubular compression sleeve having an axial bore dimensioned to receive a coaxial cable therewithin and a circumferential annular groove on a cylindrical outer surface thereof, said compression sleeve being slidably and removably disposed within said axial bore of said rigid outer shell.  
   
   
       8 . The coaxial cable connector of  claim 7  wherein said rigid outer shell is made from a substantially nondeformable material and said compression sleeve is made from a deformable material, and wherein when said compression sleeve is moved toward said connector nut, said compression sleeve is longitudinally compressed such that an annular portion of said sleeve underlying said groove is forced radially inwardly.
